Abstract
The effect of the state of nutrition of 18 children with Stage IV neuroblastoma at diagnosis and during initial therapy, was evaluated with respect to treatment delays, drug dosage alterations, tumor response, days to first event (relapse or death), and survival. All patients received similar therapy (CCSG protocol CCG 371). Based on nutrition staging at diagnosis, nine were classified as malnourished; four were randomized to receive total parenteral nutrition (TPN) and four peripheral parenteral nutrition plus enteral nutrition for 28 days (through 2 chemotherapy courses), and one died before randomization. Nine were nourished at diagnosis; seven received a comprehensive enteral nutrition program and two received TPN. By life‐table analysis, the duration of remission was significantly greater in the nourished than the malnourished (P < 0.01) and a trend towards improved survival was evident at one year (P = 0.08). The median length of survival for children nourished at diagnosis was approximately 12 months, whereas those malnourished had a median survival of only 5 months. Nine children remained nourished or were becoming renourished during the first 21 days of therapy, and one of these had treatment delays and decreased drug dosages. Seven were becoming malnourished or remained malnourished during this period and six had treatment delays (P < 0.01). These data support the idea that nutrition staging at diagnosis and during initial treatment should be an integral part of protocol design and initial evaluation of children with Stage IV neuroblastoma.
